Basic knowledge of boutique coffee roasting Yang family roaster coffee roaster Italian blending

The idea of roasting coffee over fire probably came from Ethiopia in the 13th century. In the following 700 years, people did not make much improvement to the roasting techniques of coffee. At that time, most people baked coffee at home or in coffee shops and made coffee directly from freshly baked beans.

It was not until the mid-19th century that cylindrical coffee roasters were invented. From the beginning of baking with open fire to the current baking with gas or electricity, people are constantly innovating the design concept of the baking oven. In the 20th century, a modern industrial baking furnace was invented for the first time. At first, the roasters that people built were huge. Since then, the heat conduction system of the baking furnace has been improved. At that time, roasters cooked raw beans with fast-flowing hot air, while most of the industrial roasters we use today are flipped. The coffee is constantly flipped and heated evenly at a temperature of 240℃. After 8-20 minutes, the fragrant coffee beans are freshly baked.
